[0002] The tail rope rotation detection device for mine friction hoists is a key safety device used to monitor the rotation status of the hoist tail rope. Its main function is to detect the rotation angle, angular velocity and abnormal rotation of the tail rope in real time, prevent hoisting system failures caused by tail rope rotation failure, and ensure the safety and reliability of mine hoisting and transportation.

[0003] Currently, existing technologies have the following shortcomings: In existing technologies, tail rope rotation detection usually relies on manual observation or simple mechanical contact detection, which has problems such as low detection accuracy, poor real-time performance, and susceptibility to environmental interference. Traditional detection devices cannot accurately monitor the number of rotations, angle, and speed of the tail rope, and mechanical contact can easily lead to component wear, affecting the reliability of the detection.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-5 As shown, a tail rope rotation detection device for a mining friction hoist includes a main body 1. A movable detection component 2 is provided on one side of the main body 1. The movable detection component 2 includes a detection element 3 and an adjustment element 4. The detection element 3 includes a sensor fixing bracket 21, a sensor host 22, a magnet 23, and a tail rope rotation sensor 24. The tail rope rotation sensor 24 is external and is used to detect the number of rotations, angle, and speed of the tail rope. The magnet 23 is located on one side of the main body 1 and rotates with the main body 1. The sensor host 22 is used to receive and process the data detected by the tail rope rotation sensor 24. The sensor fixing bracket 21 is used to fix the sensor host 22 in a suitable position in the cage.

[0024] During operation, the motion signal of the magnet 23 is detected by the external tail rope rotation sensor 24, which enables non-contact measurement of the number of rotations, angle and speed of the tail rope. This avoids wear and detection errors caused by mechanical contact, and improves detection accuracy and device lifespan.

[0025] Furthermore, the sensor host 22 can store, display and transmit detection data. After the tail rope rotation sensor 24 is installed with the main body 1, it obtains the tail rope rotation parameters by detecting the motion signal of the magnet 23. The sensor fixing bracket 21 is fixed to the cage by bolts, nuts and other fasteners.

[0026] During operation, the sensor host 22 integrates data storage, display and transmission functions, and can process detection data in real time and transmit it remotely, making it convenient for operators to monitor the tail rope's operating status in real time and providing data support for equipment maintenance and safe operation.

[0027] Furthermore, the main body 1 includes a tail rope rotating assembly 11, and a ring frame 12 is fixedly sleeved on one side of the tail rope rotating assembly 11.

[0028] During operation, the main body 1 is fixedly connected to the ring frame 12 via the tail rope rotating assembly 11, ensuring that the tail rope rotating sensor 24 and the magnet 23 are coaxially installed, thus reducing eccentricity error.

[0029] Furthermore, the adjusting component 4 includes a mounting bracket 33, a rotating shaft 26 is fixedly mounted on one side of the mounting bracket 33, a rotating handle 25 is fixedly mounted on one end of the rotating shaft 26, a worm gear 27 is passed through and fixedly sleeved on the rotating handle 25, and a worm wheel 28 is meshed on one side of the worm gear 27.

[0030] During operation, the operator can rotate the handle 25, causing the handle 25 to drive the shaft 26 and worm 27 connected to one side to rotate accordingly. The transmission is achieved through the meshing between the worm 27 and the worm wheel 28. The worm 27 and the worm wheel 28 have self-locking properties. When the lead angle of the worm 27 is less than the equivalent friction angle between the meshing teeth, the mechanism has self-locking properties and can achieve reverse self-locking, that is, only the worm 27 can drive the worm wheel 28, and the worm wheel 28 cannot drive the worm 27.

[0031] Furthermore, a threaded shaft 29 is fixedly installed through the worm gear 28. The two ends of the threaded shaft 29 are movably installed on both sides of the mounting bracket 33. The threaded shaft 29 is threadedly connected to a movable plate 31 with a threaded groove. A magnet 23 is fixedly installed on the top of the movable plate 31. The movable plate 31 is connected to the mounting bracket 33 through a limiting rod 32. The magnet 23 on its top rotates synchronously with the main body 1.

[0032] During operation, when the worm gear 28 is driven by the meshing connection of the worm 27, the worm gear 28 drives the threaded shaft 29 to rotate accordingly. The threaded shaft 29 and the threaded groove of the movable plate 31 are threaded together, so that the rotational motion of the threaded shaft 29 is converted into the linear motion of the movable plate 31, thereby driving the magnet 23 to rise and fall.

[0033] Furthermore, two limiting rods 32 are fixedly installed on one side of the mounting bracket 33, and the two limiting rods 32 are inserted through and movably installed on one side of the movable plate 31;

[0034] During operation, when the movable plate 31 moves up and down, the threaded shaft 29 connects to the movable plate 31 at a single point, which may cause the movable plate 31 to wobble during the movement, thus affecting the position of the magnet 23. The movable plate 31 is then connected by the limit rod 32, which limits the movement path of the limit rod 32 and ensures the stability of the movable plate 31 during the movement.

[0035] Working Principle: In Example 1, the device uses a sensor mounting bracket 21 to fix the sensor host 22 and the tail rope rotation sensor 24 to a suitable position in the cage, ensuring that the sensor and the tail rope rotation path are coaxial. The tail rope rotation assembly 11 of the main body 1 is connected to the tail rope and rotates synchronously with it. The annular frame 12 and mounting bracket 33 fixed on its outer side provide a mounting base for the adjusting component 4 and the magnet 23. When the tail rope rotates, the main body 1 drives the magnet 23 to rotate synchronously. The tail rope rotation sensor 24 detects the motion signal of the magnet 23 to obtain parameters such as the number of rotations, angle, and speed of the tail rope in real time. After receiving the signal, the sensor host 22 processes and stores the data, and feeds it back to the monitoring system through a display or transmission module, realizing real-time monitoring of the tail rope's operating status.

[0036] In Example 2, when it is necessary to adapt to different specifications of tail ropes, the operator drives the rotating shaft 26 and worm 27 to rotate by rotating the handle 25. The meshing transmission between the worm 27 and the worm wheel 28 utilizes its self-locking characteristic to ensure the stability of the adjusted position. The worm wheel 28 drives the threaded shaft 29 to rotate. Through the threaded engagement between the threaded shaft 29 and the movable plate 31, the rotational motion is converted into the linear lifting motion of the movable plate 31, thereby adjusting the position and height of the magnet 23. The limit rods 32 on both sides pass through the movable plate 31 to limit its swing, ensuring that the magnet 23 moves smoothly along a straight line during the adjustment process, and ensuring that the relative position of the sensor and the magnet 23 always meets the detection requirements.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
